When the receiver is turned back on, the Hub unit will reconnect the battery. At the end of the
flying day it is good practice to disconnect the ECU battery as safety measure because the ecu use
a very small amount of current that can drain a 2000mAH battery in 1-2 month.
Fuel
The engines can be run using Kerosene or Diesel fuel. Kerosene is the recommended fuel if avail-
able; it produces the best user experience as the engine starts and accelerates faster, without
smoke, flames or unpleasant smell.
Diesel fuel is acceptable for most of the engines. The engine will not be damaged by using it, but
user experience will be worse, the operation will generate more flames, smoke, slower start up
and acceleration, odour, and can drip few drops of fuel out of the exhaust during startup. Power
is the same using both fuels.
Recommended Kerosene fuel is the odourless refined Kerosene (some countries call it ”Paraffin”)
used in home stoves, there are different commercial brands like “keroclair”, “Ptx200”, “Petroleum”
as it is very clean and burns without smell. JetA1 will work the same but should be carefully fil-
tered before use, but its odour can be offensive during model storage.
Use the fuel preset in the START menu to select your fuel: Kero / Diesel. The ECU automatically
adjusts start settings for each fuel.
Oil
The engine requires oil for lubricating bearings. This should be mixed at 4% with the fuel and all
lubricating is then automatically metered and applied by the engine internal components.
If you use a 20ltr fuel bottle then add 0.8l of oil. For every 3 gallons of fuel add 1 pint of oil.
Some DTE oils work well in operation but leave very little slippery residue which can cause the
bearings to sound dried out after cooling. In this case we recommend the addition of 1% percent
of 100% synthetic 2 cycle oil to the 3% DTE.
To check this, simply put one drop of DTE oil between finger and thumb and rub together. You
find DTE type oils rub through very easily, whereas 2 cycle oils stay slippery very much longer.
The opposite problem exists where exclusive use of 2 cycle oil is used as it thickens up on cooling
and can cause such drag on bearings the starter cannot turn the engine for a start. So we recom-
mend a part % oil mix as follows:
The required total amount is
4%
of oil to be mixed with the fuel.
The recommended mix is a 3% of ISO32 type of oil, (commercial brands like Mobil DTE Lite,
Shell Tellus 32, Igol 32, Cepsa Turbine 32, etc)
plus 1% of 100%
synthetic
2 stroke oil
. Plenty of
commercial brands 2T oil are available locally, just check in the bottle that the oil is JASO FC or
JASO FD compliant.
